Motor controller - Wikipedia

Motor controller - Wikipedia

A motor controller is a device or group of devices that can coordinate in a predetermined manner the performance of an electric motor. A motor controller might include a manual or automatic means for starting and stopping the motor, selecting forward or reverse rotation, selecting and regulating the speed, regulating or limiting the torque, and protecting against overloads and electrical faults.

Industrial Electric Motors and Generators Menu Electric Generators Suppliers. Generator Exciters AC and DC Review. Generators require direct current to energize its magnetic field. The DC field current is obtained from a separate source called an exciter. Either rotating or static-type exciters are used for AC power generation systems.

Line Reactors and AC Drives

Line Reactors and AC Drives

In some rare cases where a strange motor configuration or a motor with 6 or more poles is used, the motor inductance may be too low and a reactor may be needed. Running multiple motors on one drive may also result in a low inductance load and the requirement of an output reactor. Reactors at the drive output to reduce the effect of reflected wave:

Current limiting reactor - Wikipedia

Current limiting reactor - Wikipedia

In electrical engineering, current limiting reactors can reduce short-circuit currents, which result from plant expansions and power source additions, to levels that can be adequately handled by existing distribution equipment. They can also be used in high voltage electric power transmission grids for a similar purpose. In the control of electric motors, current limiting reactors can be used .

DC reactors - Schaffner

The primary purpose of a DC reactor is to smooth the current pulses in DC circuits and to reduce the damaging harmonics on the power line. Schaffner DC reactors, also called DC link reactors or DC chokes, are typically connected to the semiconductors on the DC bus of converters, inverters and variable frequency drives (VFD).

Motor soft starter - Wikipedia

Motor soft starter - Wikipedia

A motor soft starter is a device used with AC electrical motors to temporarily reduce the load and torque in the powertrain and electric current surge of the motor during start-up. This reduces the mechanical stress on the motor and shaft, as well as the electrodynamic stresses on the attached power cables and electrical distribution network, extending the lifespan of the system.
